Yeah, Midorikawa treats it as unbelievable: "I heard that, and seeing the quality of the final episode's storyboards, it seems that wasn't a total lie". Basically hyping up the final episode, but it's funny that even then he still doesn't completely believe it.

@AnimeAjay According to Hikaru Midorikawa, supposedly Ryota Nakamura spent three months on the story boards for the final DBS episode. How's that timeframe compare to a regular episode? toei-anim.co.jp/tv/dragon_s/sp…
